80C51 with 512 B/1 kB/2 kB RAM, dual I2C-bus, SPI
The I2C-bus will enter Master Transmitter mode by setting the STA bit. The I2C-bus logic
will send the START condition as soon as the bus is free. After the START condition is
transmitted, the SI bit is set, and the status code in S1STA should be 08H. This status
code must be used to vector to an interrupt service routine where the user should load the
slave address to S1DAT and data direction bit (SLA+W). The SI bit must be cleared
before the data transfer can continue.
When the slave address and R/W bit have been transmitted and an acknowledgment bit
has been received, the SI bit is set again, and the possible status codes are 18H, 20H, or
38H for the master mode or 68H, 78H, or 0B0H if the slave mode was enabled (setting
AA = Logic 1). The appropriate action to be taken for each of these status codes is shown
in Table 22.
6.4.5.2
Master receiver mode
In the Master Receiver mode, data is received from a slave transmitter. The transfer
started in the same manner as in the Master Transmitter mode. When the START
condition has been transmitted, the interrupt service routine must load the slave address
and the data direction bit to I2C-bus Data Register (S1DAT). The SI bit must be cleared
before the data transfer can continue.
When the slave address and data direction bit have been transmitted and an
acknowledge bit has been received, the SI bit is set, and the Status Register will show the
status code. For master mode, the possible status codes are 40H, 48H, or 38H. For slave
mode, the possible status codes are 68H, 78H, or B0H. Refer to Table 24 for details.
After a repeated START condition, I2C-bus may switch to the Master Transmitter mode.
